I couldn’t find anything in the search engines, so I thought I would post to see if you guys have any experience with a site-built pulley system for moving slate up and down a long roof. My initial idea was 12-18 inches of ripped plywood nailed on to roofing brackets going all the way up the roof in one section where everybody is working. Then some 1x’s or 2x’s nailed onto the sides to make for a railing. Some type of plywood crate built to fit inside the rails and to hold 15-30 slates at a time. Just wondering if anybody has ever built anything like this before? If so, how did you do it, and how did it work. I am also concerned with how to prevent any wheels or the box from getting stuck on anything on its way up or down.
We have 8-10 people roofing and everytime we need to shuffle slate up the roof, almost everybody has to stop installing to help shuffle more slate up the roof. Whereas if I had this system in place, only 2 people would be needed to raise and lower the rope.

We used a Harbor Freight electric cable winch with a 2" steel pipe across the top of the scaffold tower. A homemade rack out of pipe on the bottom like a basket with one side open. The guy uptop has the control buttons and while its going up, the ground guy is sorting slate for the next lift.

I've never seen any system such as you describe in action yet.
If you've got 8 - to 10 men there it doesn't look like they all need to be laying slate anyway from what I see in your picture.
How are you bringing them up to the eaves to begin the process ?
In a job like that I'd be bringing them up to staging height with a shingle platform hoist , slating up a ways , adding brackets and another set of planks - then work slates up by hand to that level and repeat. I'd then try and reposition the hoist to reach that first or second set of roof stagings and offload slates there and use the same process I've just described.
Your suggestion of an apparatus might work , but by the time you had the kinks worked out you could have already done it by hand.
At break and first thing in the morning work them up the roof with men at each of the upper levels . Not really a big deal from my experience.
Looks like you've left yourself some tough places to lay next to the dormers.
